Adafruit DRV8871 DC Motor Driver Breakout Board - 3.6A Max

Description

Crank up your robotics with powerful Adafruit DRV8871 motor driver breakout board. This motor driver has a lot of great specs that make it useful for a wide variety of mechatronics. In particular, the simple resistor-set current limiting and auto-magic PWM support make it super easy to use with just about any brushed DC motor.

Check out the specs for the DRV8871:

6.5V to 45V motor power voltage

Up to 5.5V logic level on IN pins

565mΩ Typical RDS(on) (high + low)

3.6A peak current

PWM control

Current limiting/regulation without an inline sense resistor

Undervoltage lockout

Overcurrent protection

Thermal shutdown

Using it is super simple. Connect your motor to the OUT terminal block. Power the board with 6.5-45VDC power on VMotor and provide the H-bridge input control on IN1 and IN2. You can even PWM the inputs and the driver chip will do the right thing.

You can set the current limiting with an external resistor Rlim. We solder in a 30K resistor by default for a ~2A current limit, however you can remove this resistor and/or solder a resistor over it to change the resistance and change the limit.

Each order comes with one fully assembled and tested motor driver breakout, two 2-pin terminal blocks and a small strip of header. Some light soldering is required to attach the header and terminal blocks but it's a simple task that can be done with basic soldering equipment.

Note: The terminal blocks included with your product may be blue or black.

Ordering full reels vs. cut reels

Adafruit NeoPixel Digital RGB LED strips come to us in 4 or 5 meter reels with a 2 or 3-pin JST SM connector on each end and separated power/ground wires as shown in the pic below. If you order a full 4 or 5 meters, you get the full reel with both connectors installed (like the pic below).

If you buy less than a full reel, you'll get a single strip, but it will be a cut piece from a reel which may or may not have a connector on it. If the piece comes from the end of the reel, the connector may be on the output end of the strip!
